Sound

The Federal Signal Model L is a general-purpose electro-mechanical siren that produces a distinctive sound and tonal quality for industrial applications. It has a low maximum pitch which provides excellent contrast to industrial ambient noise. Introduced in 1946, the Model L is still used today in many rugged and extreme environments and applications.

Model L features a universal motor and operates with 120VAC/125VDC. The Model L is also available for 240VAC/250VDC operation. The fractional horsepower motor drives a ported aluminum rotor within the specially designed stator to produce a unique sound. The recommended duty cycle is five minutes on/five minutes off. This siren produces an attention-getting 112dBa @ 10 feet (122dBa @ 1m).
